You'll need to check out part of the mozilla.org repository, where the Thunderbird site is being stored. You can: svn co https://svn.mozilla.org/projects/mozilla.org/branches/staging/thunderbird/ Please translate the file in the mozilla.org svn repository for the Thunderbird 24 What's New page, that is: /eu/thunderbird/24.0/whatsnew/index.html If you want to provide translated images, you can place them in: https://svn.mozilla.org/projects/mozilla.org/branches/staging/thunderbird/img/whatsnew/l10n/ The image names should be: ignore-threads-eu.png idn-email-eu.png Once the image is on the server, the page will automatically update the <img> tag. You do not need to change it. The page on the staging server is: http://www.allizom.org/eu/thunderbird/24.0/whatsnew
